Firstly, the definition of HPCS of fractional-order uncertain chaotic systems with external disturbance is introduced. Secondly, based on fractional Lyapunov’s direct method an adap- tive control and parameter adaptive laws are designed to achieve HPCS of uncertain chaotic systems. Finally, a numerical example is carried out to verify the effectiveness of the proposed methods.

Based on Laplace transformation and stability theory of linear dynamical systems, a new control law is proposed to assure the achievement of this kind of synchronization. Secondly, this control scheme is applied to realised CCS between four identical unified chaotic systems. Recall, that the proposed control scheme can be applied to wide classes of chaotic and hyperchaotic systems. Numerical simulations are given to show the effectiveness of the proposed method.

Recall that the studied system is generated from the modi ed L u system. First, hyperchaotic attractors, symmetry, dissipation, equilibrium points and Lyapunov spectrum are the tools used to analyse this system. Moreover, this paper presents an active controller to achieve the IMPS analysis of the system. The main results are established by using Lyapunov stability theory, and nally numerical example and computer simulations are shown to illustrate all the main results.
